Wireless cable modem Thomson TCW750-4

3

Wireless cable modem Thomson TCW750-4 – is a user-class modem with aesthetically acceptable appearance and compact dimensions that can be used in flats and small offices.

 

 Key specifications:

  • Maintenance of two DOCSIS2.0иEuro-DOCSIS 2.0 standards
  • Wireless connection of 802.11 b/gс standard with connection possibility simultaneously up to 254 of users at rate up to 54 Mbit/s
  • 4 Ethernet 10/100 Base-T ports
  • Maintenance of crypto algorithms WPA, WPA2 and WEP to wireless channel
  • Reliable, high-performance platform
  • IPv6 maintenance
  • Possibility of building VPN with IPSec encryption

Usage in convergent decisions for mobile and fixed connection

Traffic priority in accordance with IEEE 802.11e standard.

Maintenance of multiple SSID. At one device one can realize up to 4 virtual access points.

VLAN control

Improved safety

To assure connection safety both for operators and for end users several protection mechanisms are realized in TCW750-4 equipment. Built-in firewall minimizes affect of malicious software on network, as well as constantly examines contents of packages. Integrated detection mechanism DoS recognizes great number of attacks patterns an in case of detection of potential threats records their data in local log or transmits data to monitoring server.

Besides, TCM750-4 maintains powerful and effective encryption algorithms of wireless channel, such as WPA, WAP2 and WEP that provide high safety level at keeping of high speed of connection.

To restrict access to control interface with wireless router authorization of users by name and password is applied.

Data exchange data at passage between cable modem and CMTS operator BPI+ encryption is applied.
